Hemigomphus heteroclytus is a species of dragonfly of the family Gomphidae, known as the stout vicetail. It is a small, black and yellow dragonfly, endemic to eastern Australia, where it inhabits streams that reduce to trickles in summer.
Hemigomphus heteroclytus is similar to Hemigomphus gouldii, the southern vicetail, also found in eastern Australia. The genus name Hemigomphus is derived from the Greek ἡμι- (hēmi, "half"), combined with Gomphus, a genus name derived from the Greek γόμφος (gomphos, "peg" or "nail"), referring to the shape of the male abdomen. The name refers to the close relationship of the genus to Gomphus.
The species name heteroclytus is derived from the Greek ἕτερος (heteros, "other" or "different") and κλυτός (klytos, "renowned", "glorious" or "splendid"), likely referring to the presence of a yellow half-collar, absent in other members of the genus Hemigomphus.

Rare
Under 5% of wildlife watchers report a Stout Vicetail sighting in Brisbane on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 806th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Stout Vicetail in Brisbane on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Stout Vicetail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Stout Vicetail sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Gomphidae
The closest relatives of the Stout Vicetail that you can see in Brisbane (family Gomphidae, Clubtails) are Australian Tiger (about 10%) and Pale Hunter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Stout Vicetail is recorded against all the insects logged in Brisbane (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
